<b>Cowpea nodulation, biomass yield and nutrient uptake, as affected by biofertilizers and rhizobia, in a sodic soil amended with <i>Acidithiobacillus</i></b> - doi: 10.4025/actasciagron.v35i4.16994

Abstract: ABSTRACT. Sodic soils require application of amendments as gypsum and organic matter. Many types of compost have been tested in sodic soils reclamation; however, these materials often do not provide satisfactory pH reduction. A recent study reported effective effects applying mixture of gypsum and sulfur inoculated with Acidithiobacillus in sodic soils with high pH and exchangeable sodium, though the effects on plant parameters were not evaluated. The present study was conducted to verify the effects of BPK ro… Show more

“…Stamfordet al 28 observed that applying nitrogen biofertilizer showed positive impact on nitrogen uptake and nitrogen content in cowpea and same results were obtained by others for soybean 29 .The combined applications of different nitrogen and phosphorus biofertilizers on various field plants were more effective for nitrogen, phosophorus uptake compared to their single application 30 . Hence, we concluded that by applying inorganic phosphorus fertilizer along with nitrogen and phosphorus biofertilizers resulted in better nitrogen uptake by the various essential field crops than that obtained by the single usage of inorganic phosphorus fertilizer or either of the biofertilizers.…”

“…Furthermore, the reduction may be influenced by the strain of A. thiooxidans (FG 01), which is more effective and seems to be the main factor responsible for the acidification process promoting values of pH lower than 4.0. Stamford et al (2013) in a Neosoil Fluvic Sodic grown with cowpea reported a reduction in soil pH from 10.5 to 8.00. Stamford et al (2015) with cowpea in a saline sodic soil of the Brazilian Semiarid region demonstrated a reduction in soil pH when sulfur inoculated with Acidithiobacillus was applied at a rate of 3.2 t ha -1 .…”

“…They observed the effectiveness of P and K fertilization in increasing the available P and K in soil with the application of different rates. Stamford et al (2013Stamford et al ( , 2015 suggested that the biofertilizers that were produced from phosphate and potassic rocks and sulfur inoculated with A. thiooxidans may be alternative for soluble fertilizers in soil with a low availability of P and K. The increase in available K may be explained by the solubilisation of the elements in the biotite employed for production of the potassic rock biofertilizer. The effect is probably attributed to the sulfuric acid that was produced by the metabolic reaction facilitated by the oxidizing bacteria A. thiooxidans in the presence of elemental sulfur.…”

“…Therefore, using bio fertilizers is more crucial for improving fertilizer use efficiency. Inoculating seeds with nitrogen and phosphatesolubilizing bio fertilizers (PSB) significantly increased cowpea plant growth, root proliferation, nodulation, and subsequently pod yield, according to several reviews (Bohra et al, 1990 andStamford et al, 2013). Effective microorganisms (EM1) are a biofertilizer that uses three major genera of microorganisms that are common in nature: phototrophic bacteria (Rhodopseudomonas), lactic acid bacteria (Lactobacillus), and yeast (Saccharomyces).…”
